I was making my own moral ranking of personally disorders. Some occupations require a little properly channeled OCD (call it perseverance) to excel.
A Narcissist would not be a mass murderer, but I would rank them right above murdering sociopaths at the bottom of an ethical scale.
While I believe there are more sociopathic politicians than the 4% of the population would dictate, I belive that among politicians sociopaths are outnumbered by narcissists. I still think obama is a sociopath, I wonder what Romney is?
